Incident 2026-05-28 ~05:45–13:52 MSK на vds-kzntsv. ~2.5ч активного outage + ~5.5ч на эфемерной статике до окончательного fix хостером. Revised RCA: наш netplan+systemd-networkd конфликтовал с provider's expected ifupdown stack. Их start/ipadd procedure ожидает чистый ifupdown и не может auto-recover когда networkd «держит» eth0. 8 дней работало потому что networkd сам тянул DHCP. Когда что-то на стороне Rusonyx разорвало DHCP-binding — auto-recovery не сработала. Fix: systemctl mask netplan + systemd-networkd* (на running system без stop — IP и SSH сохранились), Rusonyx ребутнул VM и положил чистый /etc/network/interfaces.d/ifcfg-eth0 через свой start/ipadd. Netmask /18, gw 89.253.192.1, чистый ifupdown.

## [2026-05-28] update | vds-kzntsv DHCP outage post-resolution — после reset хостером в 13:52 MSK выяснилось что root cause — конфликт двух сетевых стеков (netplan+networkd поверх ожидаемого provider's ifupdown). Их `start/ipadd` ожидает чистый ifupdown, не мог auto-recover при разрыве DHCP binding. Resolution: mask netplan+systemd-networkd, reboot, provider положил `/etc/network/interfaces.d/ifcfg-eth0` с /18 netmask. UPDATE concepts/vds-kzntsv-dhcp-outage-2026-05-28 (revised RCA + permanent-fix § + anti-pattern + revised lessons-learned) + UPDATE sources/vds-kzntsv-incident-2026-05-28 (timeline до 14:00 + final config) + UPDATE entities/vds-kzntsv (mask /18, ifupdown stack, kernel cmdline net.ifnames=0) + UPDATE concepts/rusonyx-vps-onboarding-quirks (quirk #9 переписан про /18, quirk #10 NEW про ifupdown vs netplan stack). Memory `vds-kzntsv-rusonyx-network-recovery` переписан с новыми фактами.
